TO ALL WHOM IT MAY CONCERN;

Be it remembered that we, SAMUEL W. Bann and-EDWIN McGUInn, of theeityyf Below-Rock county, iu the State of Wisconsin, have invented aeertainncw and useful Improvement in Iron Wells; and We do herebydeclare that the following is a. full 'and exact description thereof,reference-being had to the accompanying drawings, andvto the letters ofreference marked thereon, and making a part of tllis'specifieation.

` Similar letters of reference indicate Vlike parts.`

The nature of our invention consists in providing a cylinder-point orshort section of tubular iron-well pipe, which may bedriven withfacility into any soil, clay, hard-pan, o1' gravel, arranged in such amanner that, in the act of driving, the` wirecloth filter is` perfectlyprotected from'injury by contact with gravel or rock, entirely excludingall sand from the chamber., and yet admitting a uniform full ilow ofwater to thc pump, without turning or raising thccylinder or tubing. Thesaid improved point for iron wells is .secured to the tubing in thcusual manner.

Figure 1 is a perspective view ofthe short section or driving-point ofthe wcll tube complete.

Figure 2 is a sectional view ofthe bulb-.like head of the aforesaiddriving-point detached, also showing an edge'view of the drill-point B.I

Figure 3 is a perspective view of the perforated metallic cylinder orshield, pcrfcetly securing the wire-cloth filter from harm by hardsubstances in"tl1c.earth through which the point may be driven.

Figure 4 is a perspective view .of the perforated -metallic innercylinder, around which the wire-cloth ltci" is spread, andto which it issecured by being seidcred thereto, the said metallic cylinder infalliblyguarding the wire-cloth lter from bulginginwardly from externalpenetration or pressure, and from being loosened and torn off by suctionand carried up through the pump-valve, thus`renderi-ng the pumpworthless by reason of discharging sand with the water, very soonwearing ont the valves and pump.

A, g. 1, represents the slots or perforations in the chamber of thedriving-point, and a thc upward-bevellcd elongations thereof, so thatwhen the pointisfbeingdrivcn, the perforations do not {ill with earth,the bevel wedging back the soil and leaving the'hol'e,free,'insteadofdriving the earth before it,as asquare shoulder would, the beveis alsoforming a natural channel for the water to flow into the holes downward,the lower shoulders forming a sort of dam, causing thcvimpeding -loauito be dissolvedA and drawn up by and through the pump, freeing theexternal surface of4 the chamber from earthy contact, andallon'ingan'abundantsupply of Water about the point.

The use ofthe drill-point B etl'ectually prevents th'c point fromsticking lfast when being driven through stili` clay or hard-pan, saidpoint forming a sort-of auger, hy the use of which thc well may be sunkin soft or free soil by turning the tubing like an auger, and no drivingbe required.

We Claim the combination and arrangement of the well-tube, solderediltcr, and drill-point, all substantially as and for the purpose setforth.

SAMUEL W'. BARR,

`EDWIN McGUIRE.
